C. nervously and embarrassing
D. nervous and embarrassed
答案:
A. nervously and embarrassingly
B. nervous and embarrassedly
C. nervously and embarrassing
(答案→)D. nervous and embarrassed
解析:考查形容词用法。本题中的embarrassed是由过去分词转换的形容词,用来修饰人或者与人有关的事情。形容词nervous and embarrassed对句子的主语he的情况进行解释说明;句意:当轮到他发言的时候,很紧张尴尬,他朝麦克风走了过去。故D正确。
